Acoustical Surfaces CFAB™ panels are cellulose-based acoustical and thermal panels that control and deaden reverberation and echo by reducing surface-area sound reflections.
Applications
Acoustical Surfaces CFAB™ cellulose panels can be used in any area that calls for acoustical or thermal treatment. This cellulose sound absorber and thermal insulator can be covered with fabric or other decorative material. Typical applications include but are not limited to:
- Insulation components
- Office panels
- Acoustic panels/inserts
- Molded, flat panel or lofted parts
Densities
- 3lb pcf – 1″ Thickness & 2″ Thickness
- 6lb pcf – 1″ Thickness
- 8lb pcf – ½″ Thickness & 1″ Thickness
Green Qualities
The first cellulose-based panel in the industry, CFAB™ cellulose panels are made from recycled and renewable fibers, consisting of 65-75% recycled content. This makes cellulose insulation a sustainable, alternative to traditional fiberglass and synthetic acoustical and thermal panels. CFAB™ cellulose products are recyclable and don't produce scrap during manufacturing or installation. They are manufactured with a sustainable process that reduces energy use and air pollution. Through an innovative manufacturing process, ecocell is produced as a cellulose-based product made primarily from post-consumer and post-industrial paper, with recycled newspaper as the main raw material.
Acoustical Performance
The open design and density of CFAB™ cellulose insulation panels increase sound absorption to control and deaden sound reverberation and echo. CFAB™ cellulose acoustical panels achieve high Noise Reduction Coefficient (NRC) ratings based on the density specified.
